Global distribution of primary and secondary vegetation at 1km spatial resolution
<p>This dataset provides the global spatial distribution of primary and secondary vegetation at approx. 1km spatial resolution (0.01°). It combines Hilda+ landuse/cover data by Winkler et al. (2020) and the global dataset on human influence by Riggio et al. (2020).</p> <p>The data consists of three NetCDF files: </p> <ul> <li>Primary vegetation</li> <li>Primary vegetation minimal use</li> <li>Secondary vegetation</li> </ul> <p>Primary vegetation is assigned where forests, unmanaged grass-/ shrubland or land with sparse vegetation according to the HILDA+ dataset (classes 44, 55, 66) are under full agreement of low human influence according to the global dataset on human influence.</p> <p>The same HILDA+ classes (44, 55, 66) with full agreement to be under very low human influence according to Riggion et al. (2020) are defined as primary vegetation minimal use.</p> <p>Secondary vegetation consists of forests, unmanaged grass-/ shrubland or land with sparse vegetation according to the Hilda+ dataset (classes 44, 55, 66) that are not classified as primary vegetation.</p> <p> </p> <p>Sources:</p> <p>Winkler, K., Fuchs, R., Rounsevell, M.
